Notion · San Francisco, California
About this role
## About Notion Notion is the collaborative AI workspace where teams and agents think together. We’re building one place where your knowledge, projects, meetings, and AI tools live side by side—so work is faster, clearer, and less fragmented. Millions of individuals, small teams, and large companies run their work on Notion. Our goal isn’t to ship the next feature—it’s to set the standard for how humans work together in the AI era. ## About the Role — Model Capabilities The Model Capabilities team owns the model layer of Notion AI: integrating frontier models as they ship, keeping inference reliable and economical at scale, and building new capabilities other teams can leverage. **Location:** San Francisco or New York City **In-office cadence:** Mondays, Tuesdays, and Thursdays (Anchor Days) ## What You’ll Achieve - Bring new frontier models into production quickly so they’re available to users and engineers. - Make inference reliable with better error categorization, self-healing retries, and cross-provider failover. - Own observability for the model layer to reduce time to detection and time to fix. - Build new model-level capabilities and help product teams adopt them. - Act as connective tissue across Notion’s AI teams—identify gaps, unblock others, and ensure fixes land with the right owner. ## Skills You’ll Need to Bring - **Comfort with a moving frontier:** The model landscape changes monthly. Stay pragmatic about what to adopt now. - **AI fluency as a practitioner:** Use AI tools seriously and have informed opinions on where they help (and where they don’t). - **Production AI systems experience:** Built and operated systems on top of LLM APIs (not just prototypes). Understand token economics, streaming, tool calling, context limits, and production failure modes. - **Measurement before conviction:** Define what “better” means, use evaluation to test changes, and be willing to be proven wrong by data. - **Cost and performance instincts:** Treat latency and dollars as product qualities; reason about tradeoffs between them and output quality. ## Compensation & Benefits Notion offers competitive cash compensation, equity, and benefits. For roles based in **San Francisco or New York City**, the estimated **base salary range** is **$255,000–$300,000/year** (final offer depends on factors like location, scope, and experience). ## Equal Opportunity & Accommodations Notion is an equal opportunity employer. If you’re excited about the role but don’t meet every bullet, we still encourage you to apply. Reasonable accommodations are available during the application process—reach out to your recruiter if you need one. #LI-Onsite
